TB500
Actin-Regulating Peptide for In Vitro Research
TB500 is a synthetic peptide analog of the naturally occurring thymosin beta-4 protein fragment, consisting of 43 amino acids. It targets G-actin (globular actin) and is known to regulate actin polymerization dynamics within eukaryotic cells. TB500 is structurally designed to bind actin monomers, facilitating their availability in the cytosol and influencing cytoskeletal reorganization.
This peptide is commonly used in in vitro research to explore cell motility, cytoskeletal assembly, and actin-mediated intracellular transport. Its sequence maintains the actin-binding motif of thymosin beta-4 and is unmodified, preserving native peptide folding and affinity. TB500's molecular profile supports experimental consistency in cell migration and tissue culture models.
The lyophilized form offers long-term chemical stability, enabling reproducible dosing across assay replicates.
